DYEIING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 785,283, dated March21, 1905. Application filed June 11, 1904. Serial No. 212,179.

To all. whom it may concern.-

Be it known that I, DANIEL F. WATERS, of Philadelphia, in the State ofPennsylvania, have invented certain new and useful Improvements inDyeing-Machines, whereof the following is a specification, referencebeing had to the accompanying drawings.

My invention relates particularly to certain improvements in the frameupon which the yarn is suspended and means to move the yarnsticks toprogress the yarn hung thereon.

As hereinafter described, my improvements comprise means tointermittently rotate the yarn-sticks, including ratchet-wheels on therespective sticks, pawls engaged with said wheels, a bar common to saidpawls, and means arranged to reciprocate said bar in delinite relationto the movement of a liquor-cir culating wheel.

, My invention includes yarn-sticks of poly,,'- onal cross-sectionhaving recesses between their angles, permitting access of the liquorbetween the sticks and the yarn thereon, and an improvedliquor-circulating wheel mounted upon a horizontal axis and having aplurality of blades extending parallel with said axis.

My invention comprehends the various novel features of construction andarrangement hereinafter specified.

In the accompanying drawings, Figure I is a plan view of a machineconveniently embodying my improvements. Fig. II is a verticallongitudinal sectional view of said machine, taken on the line II II, inFig. I. Fig.

III is a vertical transverse sectional view of said machine, taken onthe line IILIII in Figs.

I and II. Fig. IV shows the cross-sectional configuration -of theyarn-stick indicated in Fig. II. Figs. V and VI are transverse sectionalviews of modified forms of yarn-sticks.

In said figures the vat comprises the floor 1, side walls 2 and 3, andend walls 4 and 5 and is conveniently formed of wood. Said vat isprovided with the, false floor 6, which terminates short of the oppositeend walls 4 and 5,so as to afford passage-ways 7 8 through which theliquor 9 may have free access to the heating-coil 10 and pipe 11, whichlatter extends between the floor 1 and the false floor 6, as

best shown in Fig. II, and is conveniently perforated, so as todistribute within the body of liquor in the vat the steam or otherheating medium supplied to the coil 10 through the pipe 13, controlledby the valve 14. The chamber l5'is formed at the left-hand side of saidvat, as shown in Figs.I and II, by the partition 16, carried by theyarn-frame and held against the cleats 17, respectively attached to theside walls 2 and 3. The liquor-circulating wheel 18 is mounted to rotatein said chamber on a horizontal axis and in the direction indicated bythe arrow in Fig. II to deliver theliquor 9 from said chamber 15 overthe top of said partition 16. The upward flow of the liquor in saidchamber 15 is also facilitated by the convection-currents produced bysaid heating-coil 10. Said liquorcirculating wheel comprises a series ofblades 21, extending parallel with its horizontal axis and in radialrelation thereto, and said blades are secured at their opposite ends inthe flanged heads 23 and 24, which are respectively provided with thealined shafts 25 and 26, mounted to rotate in the stufiing-boxes 28 and29 in' the side walls 2 and 3. Said shaft 25 is provided with tight andloose pulleys 31 and 32, by which said liquor-circulating wheel may beconveniently rotated. Between the loose pulley 32 and the stufling-box28 the shaft 25 is provided with the pinion 34, which engages thegear-wheel 35 on the stationary stud-shaft 36, which latter is securedon the wall 2. Said gear-wheel 35 is provided with the eccentric 38,having the strap 39, whose rod is connected by the pivot 42 with thelever 43. Said lever 43 has its fulcrum 45 in the recesses 46 in thebracket 47, which latter is conveniently secured by the bolts 48 to theupper side bar 50 of the yarn-frame. Said frame comprises the oppositeside bars 50 and 51, which are connected by the cross-bars 52 and 53 andprovided with hangers 54 and 55, on which the lower side bars 57 and 58may be adjustably secured by any convenient fastening means, such as thepins 60, which may be removably inserted in the series of apertures 61and 62 in said hangers. Said side bars 50 and 51 respectively compriseparallel metal plates, in which the yarn-sticks 63 are mounted torotate, and each of said sticks is provided with a ratchet-wheel betweenthe parallel plates of the side bar 50. The pawlbar 66 extends betweensaid plates above said wheels 65 and is provided with pawls 67 for therespective ratchet-wheels 65 and is arranged to be reciprocated (on thebolts 68 and under the straps 69) by its pivotal connection 70 with saidlever 43, which latter is oscillated by its connection with theeccentric 38 above described.

The yarn-frame is conveniently supported in the vat by the cross-beams71, whose ends rest upon the opposite side walls 2 and 3 of the vat.Said cross-beams are connected with the side bars 50 and 51 of saidframe by the metal straps 7 2 and bolts 73 and are conveniently providedwith eyebolts 75, secured therein by nuts 76, by which the frame may beconveniently uplifted from the vat. As shown in detail in Fig. IV, saidsticks 63 are preferably of equilateral quadrangular crosssectionalconfiguration and have cylindriform concave recesses 77 between theirangles, preferably coextensive with the sticks. Such construction isadvantageous in that the yarn 78 is supported by said sticks with theminimum area of contact with the latter, so that the dye liquor 9 isfree to percolate between the yarn and said sticks 63. However, it is tobe understood that the last-named advantagemay be attained by the use ofsticks of other polygonal forms. For instance, Fig. V shows a stick 79of triangular cross-sectional configuration having recesses 80. i

As indicated in Figs. II and III, the bracket 47 and the straps 69 and 72 are provided with flanges 81 to support a cover 82, having battens 83,which rest on said flanges.

It is to be understood that the peculiar recessed form of stickaforesaid is not essential to the operation of the stick-rotatingmechanism above described. For instance, I may employ sticks of planequadrangular cross-section, as shown in Fig. VI, and it is to beunderstood that the angular edges of each of the forms of sticksaforesaid engage the yarn so as to progress it when the sticks arerotated, and thus present fresh surfaces for contact with the sticks andsubject the successive portions of the yarn-hanks to the action of thedye liquor at different depths in the tank, so as to insure uniformcoloring of the yarn.

It is tobe understood that the depending hangers 54 and 55 and lowerside bars 57 and 58 are not essential to the operation of the frameabove described and they may be omitted in machines adapted for thetreatment of yarn which does not require to be stretched during thedyeing operation.

It is characteristic of the mechanism above described that the sticks 63are automatically rotated step by step upon their individual axes indefinite relation with the continuous rotation of the liquor-circulatingwheel 18. However, it is to be understood that if the eccentric-rod 40is disconnected from the hand-lever 43 rotation of said sticks 63 may becontrolled and effected by the manipulation of said lever 43independently of the rotation of the wheel 18 and, in fact, automaticmeans for efiecting such rotation may be entirely dispensed With.

It may be noted that a liquor-circulating wheel18, comprising horizontalblades extending the full width of the vat, is advantageous inthat itinsures uniform circulation of the liquor in a stream the full width ofthe vat, it being characteristic of circulating-wheels having their axesotherwise disposed that the liquor is caused to circulate in'streamsless than the full width of the vat and tending to produce an uneveneffect of the dye upon the yarn. Moreover, it has been found in practicewith wheels of the last-named construction or arrangement that someadjunctive means must be employed to distribute the narrow streams ofthe liquorfor instance, screens or false floors which are perforatedandI find that in view of'the better distribution of liquor secured by myimproved form of circulating-wheel such adjunctive devices may bedispensed with.

I do not desire to limit myself to the precise details of constructionand arrangement above described, as it is obvious that variousmodifications may be made therein without departing from the essentialfeatures of my invention.
